A Brighton Beach woman told her family she was going to get a haircut—then disappeared, police sources said.

Elizabeth Tuul, 29, was last seen at a salon on the corner of Brighton 5th Street and Brighton Beach Avenue about 4:30 p.m. yesterday, cops said. She did not go back to her home nearby on 5th Street near West Avenue.

Cops say Tuul is 5-foot-9, and about 150 pounds. She was wearing blue sneakers and a pink sweater when she disappeared.
